TO ALL WHOM IT MAY CONCERN: v H

Be it known that I, HERRMAN I'IEMPEL, of the. city, county, and State ofNew York, have invented a new 1 and improved Bntton Hole Cutter; and Ido her-eh; declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeanduse the same, reference being had to the accompanying drawings,forming a part of this snecificution, in wl1ioh- Figure 1 is a. sideview of my improved button-hole cutter.

Figure 2 is a cross-seetion of thesame, taken on the line =2: 1:, fig.1.

Figure 3 is a detail side view of the sliding rest; and

Figure 4 is a detail edge View of the cutter or knife.

Similar letters of, reference indicate corresponding parts.

The invention relates to anew device for cutting button-holes ofdifierent lengths.

The improvements consist in having a sliding rest which is adjustedunder the knife, so as to niake the some out longer or shorter holes;and also in making the knife in one piece, wlicreby'it cannot only hemade cheaper, but also easier fastened in the jaw or arm to which itissecured'.

A and B are two arms, which are pivoted together like the arms oi'acommon pair of shears; a and b are their respective handle ends; and cand d, their jaw ends, as shown in fig. 1. To the jaw cis secured theknife or cutter C, which is made so as to cut the eye and slit ofabutton-hole. Usually the knives for cutting button holes are made of twopieces, the piece 0 for cutting the eye, and the long straight piecefforcutting the slit of the button-hole; Itwas very difficult to accuratelysecure these two pieces in the jaw, a-nd when secured, they would easilyget. out of order. By making the whole knife in one piece, I can. mucheasier adjust and secure it in the jaw a, providing simply a mortise inthe inner surface of the jaw, and keepingthe letter in position by meansof wedges, set-screws, or other suitable devices. On the jaw d isarranged a. sliding block, D,

which when, in the position shown in .fig. 1, is exactly under the knifeC, and a. button-hole can be then out, which is as long as the wholeknife. By moving the block D towards the pivot of thejaws a less portionof it will be brought under the cutting edge, and a shorter hole will beout on i and it can be so regulated that holes of any desired length,but none longer than the knife, can be out on this machine. The block Dis held on the jaw 01 by means of straps gg fitting around the jaw, asseen in'figs. 1, 2, and 3. One of the sides of the jaw is provided witha row of small holes, as shown in fig. 3, into which a spring-catch, 1.,fits, so that thereby the block D can he firmly held in any desiredposition. i

I claim as new, and desireto secure by Letters Patentj The sliding blockD when secured.- to the jaw d by means of strapsg g, and when held inposition by a spring-catch, 71 fitting into one of a. series of holesarranged on one side of the jaw d, all as set forth.
